Archive linked by name to the Clevo A110SU platform, holding firmware in two sizes, 2 MB and 4 MB, most likely BIOS images for boards fitted with different SPI flash capacities. Read the marking on your flash chip first and pick the image whose size matches it exactly, since a file larger than the chip will not fit and a smaller one will flash incorrectly. Dump and keep the original contents with your programmer before writing, so the board can be restored if the new image fails to boot.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @vinafix_bios. Enginerys does not host this file.
